Improve the demo example using longer text illustration

[AyanGhatak]

The demo example can be improved in these following fashion:

• The demo example here uses a relatively shorter(wrt the width and height of the container) and trimming may not be apt here. So it would be good if we use a longer text to illustrate the fact.

• The below mentioned instruction may be used with some highlight to catch the first attention of the end user viewing the sample.

Change the text in the textbox to see the effect.
